Learn how the Garmin sleep data files are categorized and defined.
- The ENHANCED_FINAL one with the longest sleep period
- The ENHANCED_TENTATIVE one with the longest sleep period
- The AUTO_FINAL one with the longest sleep period
- The AUTO_TENTATIVE one with the longest sleep period
The data could be auto-confirmed, but the sleep window could have been manually adjusted, or the sleep data itself is entirely manually entered. Possible values:
NOTE
Many Garmin devices attempt to auto-sync data during the night while the user is asleep and the smartphone is charging. This may result in an incomplete Sleep summary record. It is important to update sleep data with the most recent data to get an accurate and full representation of the sleep window.
Generating Sleep Data
Users may generate sleep data in three different ways.
- Some older Garmin devices (e.g. first generation vívofit) allow users to manually place the device in sleep mode.
- Newer devices do not have this option and instead auto-detect sleep if it occurs between the user’s Bed/Wake time range configured in Garmin Connect.
- Users may also self-report sleep information using Garmin Connect.
Tips For Getting Accurate Sleep Data
To ensure the most accurate sleep data:
- Make sure that your sleep and wake windows are set correctly (see Setting Sleep and Wake Window Times in Garmin Connect). If your sleep schedule changes, update your sleep and wake windows to ensure the most accurate sleep measurement.
- The watch must be worn at least two hours before bedtime. Many Garmin devices attempt to auto-sync data during the night while the user is asleep and the smartphone is charging. This may result in an incomplete Sleep summary record. It is important to update sleep data with the most recent data to get an accurate and full representation of the sleep window. You can refer to more details on How Does This Feature Work and Advanced Sleep Monitoring Watch Compatibility.
Understanding Sleep Summary Data
Unlike Daily Summaries which are associated with a given day on a midnight-to-midnight basis, Sleep Summaries are associated with a user’s overnight sleep range. Most will start on one calendar day and end on the next calendar day, but it is possible for two different Sleep Summaries to begin on the same day if, for example, the user goes to bed after midnight, wakes up, and then goes to bed prior to midnight the next evening.
However, it is worth mentioning that, for the sleep starting on one calendar day and ending on the next calendar day, the calendar date of the sleep summary would be the next calendar day.
